Interface RasterOp

This interface describes single-input/single-output
operations performed on Raster objects. It is implemented by such
classes as AffineTransformOp, ConvolveOp, and LookupOp. The Source
and Destination objects must contain the appropriate number
of bands for the particular classes implementing this interface.
Otherwise, an exception is thrown. This interface cannot be used to
describe more sophisticated Ops such as ones that take multiple sources.
Each class implementing this interface will specify whether or not it
will allow an in-place filtering operation (i.e. source object equal
to the destination object). Note that the restriction to single-input
operations means that the values of destination pixels prior to the
operation are not used as input to the filter operation.

filter

Performs a single-input/single-output operation from a source Raster
to a destination Raster. If the destination Raster is null, a
new Raster will be created. The IllegalArgumentException may be thrown
if the source and/or destination Raster is incompatible with the types
of Rasters allowed by the class implementing this filter.

getBounds2D

Returns the bounding box of the filtered destination Raster.
The IllegalArgumentException may be thrown if the source Raster
is incompatible with the types of Rasters allowed
by the class implementing this filter.

createCompatibleDestRaster

Creates a zeroed destination Raster with the correct size and number of
bands.
The IllegalArgumentException may be thrown if the source Raster
is incompatible with the types of Rasters allowed
by the class implementing this filter.
